Thin Film Optical Coating Lens

1-8 of 8

Optical thin film is one or more thin layers of material deposited onto a substrate. The wavelengths of the refracted or reflected light change when light passes through the lens with optical films treated. Due to this feature, the thin film can be designed to increase the reflectivity of the lens or the transmittance of light. Furthermore, it is possible to allow the specific range of wavelengths to pass through the lens. The process we use is the evaporation physical vapor deposition to achieve the thin film layers.
